My lovely 3 year old son has suddenly developed an arrogance. When I tell him off I get answers such as “er mommy- don’t shout” “don’t talk to me like that” “say please” . It’s infuriating! I put him in the naughty corner, then explain to him why he was in the wrong. But i can’t seem to get him to understand- it’s ok for me to talk to him with authority but he shouldn’t to me. I was very aware I was becoming one of those “shouty moms” and soon nipped it in the bud. But he still seems appalled if I dare to speak to him with any authority!!! Help!!!!! Suggestions?
